  2. 1. Modelling of the pyrolysis of large wood particles

    Author : Michel Bellais; Krister Sjöström; Björn Zethraeus; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drying; modelling; pyrolysis; shrinkage; wood; Chemical energy engineering; Kemisk energiteknik;

    Abstract : Wood is an interesting alternative to fossil fuels. It is CO2-neutral and widely available. However it is a difficult fuel to handle which features a low energy content. Thus technologies for wood thermal conversion need to be improved. READ MORE

  6. 4. Computational strategies in flame-spread modelling involving wooden surfaces

    Author : Jörgen Carlsson; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flamspridning; computational methods; pyrolysis modelling; fire modelling; fire growth; flame spread; Computational Fluid Dynamics; CFD; brandtillväxt; brandmodellering; pyrolysmodellering;

    Abstract : Various approaches to flame-spread and fire-growth modelling are discussed and are evaluated using experimental results from different tests. Use of Computational Fluid Dynamics, CFD, in fire modelling is discussed and the performance of different CFD codes in wall flow modelling is analysed. READ MORE

  7. 5. Numerical modelling of biomass thermochemical conversion and potassium release

    Author : Seyed Morteza Mousavi; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical modelling; particle model; bed model; CFD simulation; biomass; pyrolysis; ; combustion; gasification; potassium release; alkali;

    Abstract : The use of biomass as a renewable source of energy has been increasing over the past few decades, and biomass is regarded as a promising replacement for fossil fuels. Thermochemical conversion of biomass is a common approach for biomass utilization with a relatively short conversion time. READ MORE
